NAT IP PUBBLICI HDSL

[hvcuser]

Ciao ho un problema ha configurare il NAT (uno a uno) degli IP pubblici sulle macchine sulla LAN.

La linea è una HDSL Telecom
Punto Punto XX.XX.122.32/255.255.255.252

IP Pubblici XX.XX.69.112/255.255.255.248
GW 94.86.69.112

LAN 192.168.1.0/24

Fino ad oggi il cliente non ha avuto bisogno di usare gli IP pubblici ora devo fare un cambio di configurazione come segue :

IP pubblico xx.xx.69.113 NAT su -> 192.168.1.40
IP pubblico xx.xx.69.114 NAtT su -> 192.168.1.41
e cosi vià.

Ho provato ad usare una Loopback per il primo IP pubblico ma mi sembra che non funzioni (volevo usare una loopback per ogni ip pubblico).

La cfg del router è la segente :
